Why are leaves considered living things?

They fulfill a characteristic of living things they have 
Respiration: Trees "breath in" carbon dioxide and breath out oxygen
Sensitivity: They react to things around them
Growth: Through photosynthesis and by absorbing nutrients, minerals and water through their roots, trees do grow
Reproduction: They have pollen and seeds 
Excretion: They excrete oxygen

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
